Generate co-working billing from verified desk and meeting room usage captured directly from access systems. Fixed fees and variable usage combine into an accurate, itemized bill, replacing manual sign-in sheets and disconnected booking tools.
Turn manual sign-in sheets into verified usage that bills members automatically.
01.
The Device Attestation module signs access and booking events at source, so a billed hour of meeting room use is a verified fact rather than a logbook entry.
02.
Desk check-ins and room bookings accumulate per member in real time, building the variable portion of the bill without manual tracking.
03.
Fixed membership fees and included allowances are encoded per plan, so the contract knows what is bundled before charging for overage.
04.
The Invoices and Billing module combines fixed fees and metered overage into one itemized invoice at period close, with no reconciliation.
05.
The Audit Logs module timestamps every access and booking event, giving members a transparent basis for each line on their bill.
06.
Because each charge traces to a signed access event, a member can verify usage rather than contest an opaque total.
Follow one member from access through metered usage to an automatically itemized invoice.

Cerulea decomposes workspace billing into modular contracts. Each layer attests access, meters usage, aggregates the period, and invoices without manual sign-in sheets or reconciliation.
Verified usage billing is a horizontal capability. Here is how different workspace actors put the automated meter to work.
Bill members from signed access data across locations, ending revenue leakage from untracked room use and the reconciliation of sign-in sheets.
Key Asset Types
Receive an itemized bill where every charge traces to a verified access event, replacing disputed totals with a transparent usage record.
Key Asset Types
Read live utilization per resource to plan capacity and pricing, drawing occupancy insight straight from the same signed events that drive billing.
Key Asset Types
Whether you are bridging access control and booking platforms or capturing check-ins from a door reader, Cerulea routes both into one usage billing record.
For operators on access control and booking systems. Access and booking data translate into signed on-chain usage records through the API gateway automatically.

Building a workspace billing system with device-attested usage, plan allowances, and automated invoicing from scratch requires specialised proptech and billing engineers. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects proptech billing integration benchmarks. Wiring access and booking systems, encoding plan allowances, and automating invoicing for an average operator takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your usage and billing rules into pre-audited WebAssembly binaries and provisions the attestation and invoicing layers instantly.
